IMPROVEMENT IN BOXES FOR PRESERVING AND TRANSPRTING BUTTER, &c.

Specification forming part of Letters Patent No.152,223, dated June23,1874; application filed June 2, 1873.

To all whom it may concern:

Be it known that We, WM. R. GILLETT and GEO. W. HARTsHoRN, of WhitePigeon, St. J oseplrconnty, Michigan, have invented certain new anduseful Improvements in Butter- Ireservers, of which the following is aspecification:

The nature of our invention relates to an improvement in boxes forpreserving butter and other articles; and it consists in lining theinsides of the boxes in which the articles are packed for transportationwith sheets of non-conducting material made from the pulp of poplarWood, as will be more fully set forth hereafter."VY

The accompanying drawings represent our invention.

a represents an ordinary box, of any shape or size, in which butter,tobacco, or other articles are packed for transportation. This boX islined inside with a sheet, c, of any desired thickness, made fromtheipulp of poplar Wood; and these sheets, forming a non-conducting'substance, preserve the butterand other articles packed in the boxes inthe most eective and We disclaim such.

manner -from all changes of the surrounding atmosphere.

Where these sheets have been saturated with Water, and the boxes thenpacked with butter, the butter is preserved from melting in the hott-estWeather.

We are aware that casks for the transportation of oil have been linedWith paper-pulp, Where the pulp is made from poplar Wood it will absordlnore or less Water, and retain it almost indenitely, and thus keep anyarticle packed in the box moist and cool. Vhere the pulp is made frompaper stock it is almost impermeable to Water, and hence will not serveas a preserver to articles as above described.

We claim- A box, for the preservation of butter and other articles,lined with wood-pulp, substantially as shown and described.
